Philips M3500B manual Restrictions for Use, Immunity Level

Electromagnetic Compatibility

Once the source is located, attempt to attenuate the EMC coupling path by distancing the defibrillator from the source as much as possible. If assistance is needed, call your local service representative.

Restrictions for Use

Artifact on the ECG caused by electromagnetic interference should be evalu- ated by a physician or physician authorized personnel to determine if it will negatively impact patient diagnosis or treatment.

Immunity Level

The EMC standards state that manufacturers of patient-coupled equipment must specify immunity levels for their systems. It is recognized that the Heart- Start XLT defibrillator/monitor is designed to receive and amplify low level signals in the same bandwidth as the interference.

	Immunity is defined in the standard as the ability of a system to perform with-
	out degradation in the presence of an electromagnetic disturbance. Degrada-		13
	tion in ECG quality is a qualitative assessment which can be subjective.
	Caution should, therefore, be taken in comparing immunity levels of different
	devices. The criteria used for degradation is not specified by the standard and
	may vary with the manufacturer.
